CONCRETE-MOLD.
Specification of Letters Patent.
' Patented Apr. 12,1921.
Application led January 14, 1920. Serial No. 351,327.
My invention relates to molds which are used in forming concrete walls.
This invention is an improvement upon my earlier invention disclosed in Patent No. 13211811 of Dec. 16, 1919. r
Objects of this invention are toprovide a concrete mold which may be used to construct a wall and may be moved to successively advanced positions along such walls; which may be adjusted to provide for a corner in such wall; which may be adjusted to provide a continuous hollowspace in the wall where a right angle corner occurs; and to provide an improved means for allowing such molds to beV readily disengaged from the wall. n
Other objects are to provide an adjustable mold which may also be readily and quickly disengaged from the work; to provide an expansible end gate for said mold which will lit Vand close one end of said mold in all .positions of adjustment, and which may readily be removed from the mold and from the work; and to provide an eXpansible removable auxiliary core for producing a continuous space within the wall when corners are formed.
In the drawings:
'Figure 1 is a perspective view of the mold adjusted so as to form a corner portion of a wall. j
Fig. 2 is a transverse sectional view through one of the adjustable members and through the auxiliary core block.
Fig. 3 is a perspective view of the auxiliary core block.
Fig. f1 is a perspective view of a removable end gate. l
The mold comprises side walls 1 and 2 which are reinforcedv along their upper and lower edges by angle irons 3 and l respectively, such angle irons being-j oined at intermediate portions by vertical bracing angle irons 5. j l
The distance between the walls 1 and 2 may be adjusted by means of the telescoping tubes 10 and 11 which are adapted to be locked in any desired position of adjustment by means of a set screw12. These tubes are provided with an opening 13 in their lower portion which snugly fits the rods G and 7,
. and forms a pivoted connection therewith,
and with an elongated opening 14: in its upper portion which allows lateralmotion of the rods at the upper portion of these tubes. These tubes may be finished by providing caps 15 which are threaded upon the ends of the tubes. The upper portions of the rods 6 and 7 areA bent toward each other and are threaded in opposite directions as shown at 16, such threads being preferably coarse. The threaded portions are adapted to be loosely engaged by the hubs 17 Vof, a turnbuclrle 18 so that such end portions may be drawn toward each other or forced away from each other, to either adjust the horizontal width of the mold or to aid in releasing the mold from the concrete wall in a manner to be described later. Upon the tube 10 is slidably mounted a strap member 19 which is adapted to be clamped in position by means of theV screws 20. This strap holds a central core member 21 in adjusted position between the side walls 1 and 2 and allows the mold to be used for making hollow concrete walls. The core is tapered downwardly to facilitate the withdrawing of the mold. j
When it is desired to form a corner portion of a wall, an auxiliary core 22, Fig. 3, is positioned between one side wall and the core by hooking the prongs 23, carried by such auxiliary core, into slots 24 and 25 formed respectively in the central core wall and in the outer wall. This auxiliary core is formed of two telescopic members which form a hollow box. A spring 26 is positioned within this auxiliary core 'and is located adjacent its lower portion for causing such lower portion to press against the walls ,of the central core 21 and outer wall 1. Y j
An end member, or gate, 27 is'detachably and pivotally connectedby means of bolts 28 which pass through holes in the upper pon tion of the side walls*` 1 and 2 and through any one of a plurality of spaced holes 29 formed adjacent the upper side edge of the end member 27. The end gate 27 is telescopic, that is to say, it is formed of two tions overlapping. To secure the lower por-` tion of this member 27 in position, latches 30 pivoted at 31 to the side walls l. and 2, are,
employed. These catches are provided along their lower edges, with a plurality of apertures 32 oorresponding'in number and in spacing to the apertures 29, such apertures receiving pins 33 secured to each side oi the end gate 27 adjacent its lower portion.
When it is desired to remove the mold the turn-buckles 18 are turned so as to draw the end members 16 of the rods'G and 7 toward each other and cause .suchV rods to pivot about the lower opening 13 formed in the 'tubes 10 and 11. vThis pivoting action of the rods causes the side walls of the mold to diverge, that is to say, the lower portion of the mold i'laresor moves outwardly away from the concrete wall, The latchA members fare then disengaged Jrom `the'pins 33 and the end member 27 is swung upwardly4 about the bolts'28. liiasmncli as the core 21 and the auxiliary core 22 are both tapered downwardly they are readily withdrawn with the rest of the mold. l V
l/Vhen it is desired to produce a straight portion of a` wall, the expansible or telcscopicend gate, F 4, may be employed.
Y The end member 27 is then removed by removing the bolts 28, and the latch members 30 are turned upwardly about the pivot points 31 so that such latch members are out oit the way. The end gate, Fig. il, comprises two similar members 34L and 35 which consistoi: right angle plates with the end portions overlapping. Between the side walls 36 and 37, -bo'wedsprings 38 are adapted to be positioned in such a manner that the shoulders v39 ot the springs, bear against such walls'and tend to cause suoli end gate f to expand. rlhe projecting portions 40 of j eo 1. A mold for concrete work,
these springs pass into openings al formed in the side members 1 and 2.
I claim: l comprising side walls; meansii'or holding said side walls in spaced relation, an end gate comprising a pair otmembers having overlapping end port-ions and rearwardly extending flanges pivotally connected at theirupper corners with the upper corners of said side walls, and` a latch for temporarily holding the lower portion oie said gate in position.
